NORMAL. 
BY A. C. PAGE. 
The Physical Science Laboratory, now nearing completion, stands 
midway between the Auditorium and the Gymnasium at the north 
end of the quadrangle. 
It is of fireproof construction, and is 112 feet, 6 inches long, 
64 feet, 6 inches wide, and, from the ground floor, is four stories 
high. 
The foundation is of Cedar Falls limestone and cement, the 
first story is built of Bedford, Ind., limestone, and the three stories 
above this are of Gladbrook red pressed brick, with a belting of 
Bedford stone between the third and fourth stories. Mason City 
hollow brick are used in the structure of the inner walls, and the 
ceilings and side walls are finished with hard plaster. 
The floors and roof are made of concrete reinforced with ex- 
panded iron, the floors being finished with three inches of cement 
with colored border, and the roof with S tile. The roof-gutters 
and ventilator are of copper, the doors and casings are of quarter- 
sawn oak, and the stairs of iron. 
The tables and apparatus cases were built at the school, of oak, 
Alberine stone being used for the table tops of hoods, and for the 
tables of weighing rooms. 
The heating plant of the building includes the indirect fan sys- 
tem for day heating and ventilation, while the direct steam heating 
is employed when the laboratory is not in use, thermostats in all 
the rooms controlling the temperature. The building is furnished 
throughout with electric lights. 
The laboratories are supplied with water, steam, gas, compressed 
air, electricity from a storage battery, and both the direct and al- 
ternating currents from the school and city plants respectively. 
The ground floor provides three rooms to be used temporarily by 
the Geography department, a cloak room, two toilet rooms, and a 
store-room connected by a dumb-waiter shaft with similar rooms 
on the floors above.
